Hey guys great thread. I have had a look but would like some recoomendations as to what numbers to use on my R33 GTS-t. This car will be used predominantly on the track and I prefer 17" wheels (thinking of Rota grid, or P45R or something similar). Im also thinking of going with a staggered set up (9-9.5 rear and 8-8.5 front). I want to run some nice wide tyres also. Questions is, what do those who do track days recommend from their experience?

Cheers

Amir

Thank you to everyone within this thread that answered my questions and provided info, and ultimately helped me select my new wheels (width and offset) Here's the end result (minus big brake kit awa

Thought I'd share my setup since there doesn't seem to be much info/examples out there for this particular setup. Perfect for spirited driving on back/mountain roads, not so ideal for daily driving or

Hey just want a quick answer. Going to buy a set of Lenso D1R's for my daily R33. Would 18x9 +32 (Front) sit flush in the guards

18×10 +22 (Rear) sit flush in the guards

Or what issues am I gonna get

Just like to hear some feedback to help me out.

Assuming Gtst. Fronts will sit inside about 10mm, and rears outside about 15mm. This depends heavily on camber though. I have 18x10+38 which after resetting camber to 0 now sit flush, maybe the tiniest bit of poke, whereas previously looked like they had heaps of room.

12mm wider rim, so 6mm either side. But 8mm larger offset, so will sit in 2mm more than 18x9+32.

You'll also have clearance problems on inside with offset larger than around +25 with 9.5" wide rim.

Best if you learn how to calculate offset, or use a calculator on the net.

My recommendation would be to use 18x9.5+22 with 235s and roll guards to fit. Not too difficult or expensive and proven to be a good combination for 33 gtst.

Yeah it is a gtst. Thanks for your help...if i went 18x9.5 +40 in the front, would that sit flush with guards?

The lower the offset the more likely it is to get to flush

I went for a staggered set of track rims last year (17x8.5 +30 front and 17x9.5 +38 rear) but changed to a square setup this year (17x9 +35 with 255/40 tyres) for the increased frontend grip and being able to rotate the wheels around the car as they wear.

What's a good offset for Rota Grid Rs in 18x9.5 all round on a 33 gtst? Thinking +35 all round. Will only go as far as rolling my guards.

Cheers

I think heaps of people run +22 all around with little tyre. Might want to check front clearance before you go putting money down.

Did you notice any oversteer with the square setup?

Didn't notice a difference in oversteer with that change. Your suspension setup, alignment and how you drive the car will affect that.

Skyline model = R33 GTS-T

Wheel diameter = 18

Wheel width = 18X9.5 Rear - 18X8 Front

Tyre size = 255/35/18 Rear - 235/35/18 Front

Modifications to fit = Guard Rolling

Offset? Photos?

Agreed, you'll definitely run into inner clearance issues with +35.

Honestly, if you're willing to roll guards just get +22 with 235/40/18s and be happy. I didn't get 9.5 +22 and sometimes wish I did.

Im thinking of getting 17x9 +25 for my r33. The guys at Rota recommended this and said the widest tire I can run would be a 255. They also said I will have better clearance with +25 than with +35.

Does this sound right to you guys?

Cheers

      For the record, I hate the colour. Even if I'll never see it again, I know its in there.

      This is another issue I'm fixing. This little valve stops all the oil from draining to the sump when the engine is turned off. What happens eventually is that the engine is a little noisy and has the oil pressure light on for a few seconds after turning it on. Basically it takes a few seconds to build the pressure when all the oil has drained. This valve is a non serviceable part and is attached to the oil filter housing, BMW suggests to replace the entire housing if this valve fails.  As it turns out this valve can be removed and that means you can get an aftermarket replacement, which I did. The failure, for me at least is that the valve doesn't seat properly after a while, which I've demonstrated. The new one is a ball end and always seats properly.

      Welp don't know if this is good but I can hear a sizzling sound in my battery Hope I didn't fry it. Turns out a bad battery in the multi meter will give a false reading (likely what happened when I said I had 15x volts), swapped the battery and monitoring now. I'm hoping that sizzling sound is just the equlisation charging

      Yeah I'm happy to talk to whoever, I don't want to take ownership or even manage it if they don't want but I can probably help with hosting on the sau setup. It's a great resource and should be protected.

      So, got some bits..   New oil filter housing gasket (main problem I'm trying to fix -see leak above)  While you're in there's: New belts, pulley and tensioners.  Vanos oil line New oil drain valve New water pump and pulley  New fumoto valve (all my cars have these). Some of this stuff seems ok now that I've pulled it out but I still have no idea how old it all is.  The belts looked fine and then I noticed this. Like somebody has hooked it with a pick.
